DEVICE FOR MANIFOLD COPYING.

' SPECIFICATION forming part of Letters Patent No. 297,556, dated April 29, 1884.

Application filed September 20, 1883. (No model.)

1'0 all whom it may concern.-

Be it known that we, H. G. BARLOW and J B. BARLOW, of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improve ments in Devices for Manifold Copying; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in devices for manifold copying, the object being to facilitate the preparation of duplicate copies of writing by reducing the number of detached copying and blank sheets to the minimum.

With these objects in view our invention consists of blank sheets divided into three equal sections by lines of perforations, and printed in the manner herein shown and de scribed, whereby the-sections may be folded upon each other with a single sheet of copying-paper in such manner that matter written upon one section will be reproduced upon the other two.

In the accompanying drawings, Figure 1 is.

a view showing one side of one sheet and the opposite side of a similar sheet, and Fig. 2 is an end view of the blank as it appears when folded with a sheet of copying-paper having both of its faces carbonized.

The blanks are divided into three equal sections, A, B, and O, by lines E of perforations, which adapt the sections to be folded upon each other, and to be separated and distributed as required. The sections A and O are printed upon the same face of the blank, while the section B is printed upon the opposite face thereof.

The arrangement of the printing upon the sections is clearly shown in Fig. l of the drawings. It should be observed that the printing is arranged so that when the sections are folded upon each other the blank spaces between the printed lines will register. The

copying-sheet F (shown in Fig. 2 of the drawings) is supposed to be carbonized on both sides; but paper carbonized on one side will I do as well, though perhaps not quite as convenient to handle.

In using the paper having both faces carbonized, a sheet of sufficient size to cover two of the three sections of each blank is employed. Such a sheet is laid over the printed side of section A and the unprinted side of section B. The section 0 is now folded to the left and laid upon the copying-paper covering the unprinted side of the section B. Then the two sections B and O, with the interposed copying-paper, are folded to the left and laid upon the copying-paper covering the section A. The printed surface of the section B becomes the uppermost, as the result of folding the blank in the manner described, and this section is accordingly written upon with a pencil, and the matter written is duplicated upon each of the sections A and (3. .When copying-paper having only one side carbonized is employed, a sheet sufficiently large to cover the entire blank is laid, with its carbonized face down, upon that surface of the blank exposing the printed side of the sections A and O. The. outer end of the copying-paper, is then folded to the left to the width of one section of the blank, to' expose its carbonized face to the printed side of the section 0, which is now folded upon it. The sections B and O, with the interposed copying-paper are then folded upon the sec tion A, and the printed surface of the section B, being uppermost, is written upon with a pencil, with the effect before described.

It will be seen that with one blank sheet, and with a single sheet of carbon-paper, two duplicates of the written matter are produced, whereas two detached sheets of copying-paper have heretofore been necessary to get the same number of copies. The old method is objectionable on account of the number of sheets to be adjusted and cared for, and to the shipping-clerk, who carries the sheets from place to place, the handling and care of the sheets is a source of great annoyance.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is- 1 In testimony whereof We have signed this 19' consisting of it sheet of paper divided into three specification in the presence of two subscribing equal sections by lines of perforations, and witnesses.
